The UMSL Digital Library is designed to help you discover content through dynamic searching. Below there are shortcut links to searches for the most popular subjects represented in the library, most of which are from the vast historic collections of the St. Louis Mercantile Library. There are buttons for different types of materials and a timeline for the various decades. Selecting any of these will pull up every object in the Digital Library tagged with the corresponding value. In most cases, more results will return than you are interested in. Narrow your search by selecting additional constraints from the sidebar. As you add or remove constraints your search results will be winnowed down to a smaller and smaller pool of objects.
